The syntheses of (+)-neamine 1, (-)-neamine ent-1 and their positional isomers 2, 3, ent-2 and ent-3 are reported as potential new scaffolds for novel aminoglycoside antibiotics. These isomers exhibit similar inhibitory activities, as shown using an in vitro translation assay. A simple model is proposed to explain this lack of stereospecific binding to the ribosomal RNA.
据报道,(+)-neamine 1,(-)-neamine ent-1及其位置异构体2、3,ent-2和ent-3的合成是新型氨基糖苷类抗生素的潜在新支架。这些异构体表现出相似的抑制活性,如使用体外翻译分析所示。提出了一个简单的模型来解释这种与核糖体RNA立体定向结合的缺乏。
